SPEG'FICATION forming part of Letters Patent No. 630,531, dated August 8, 1899.

Application filed February 28, 1899; Serial No. 707,133. (No model.) I

T0 all whom, it may concern:

Be it known that I, CLARE ERNST, a citizen of the United States, residing at Bay City,inv the county of Bay and State of Michigan, have invented certain new and useful Improve-4 ments in Vises, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has reference to an improved vise particularly designed for use in holding metal tubing; and the invention consists in the peculiar construction, arrangement, and combi-nation of the various parts of -the vise, as will be more fully hereinafter described and shown. Y j 1 Figure l is a perspective view of the vise. Fig. 2 is a horizontal central section therethrough, partly in plan. Fig. 3 is a section` taken on line a, Fig. 2. Y tal section through the portion of the mechanism shown in plan in Fig. 2, the parts being in their locked position.- Fig. 5 is a section taken on line y y, Fig. 2; and Fig.l 6 is-an end elevation of the vise.

The reference-letter A designates a standard, which is swiveled in any suitable manner upon the base-plate B and is locked thereto by means of clamping-bolts C. The standard.l is provided with a horizontal tubular head D, upon one end of which and preferably integral therewith is an annular lange E. Swiveled to the flange is oneof the clamping-heads F, carrying a multiple of clamping-jaws Gr.A

Any suitable means may be employed for swiveling the head to the flange; but the conv struction I preferably adopt is as follows: -In the face of the head adjacent to the flange I form an annular undercut groove 0 and inv said groove are arranged the heads h of boltsc, which are adapted toeXtend into and through the lange, as shown. The head thus formed may be rotated into any desired position and is clamped in said position by means of th clamping-nuts e. i

The head F is centrally apertured at f, and arranged within the tubular head D and eigtending through the aperture referred to is a tubular supporting arm or stem H, which carries upon its outer end a head inthe form of a nut J, secured to the stem by means of pins g.

Fig, 4 is a horionrshown out of engagement.

The letter K designates a complementary clamping-head provided` with a multiple of grooved clamping-jaws L, which correspond to the clampingfjaws upon the head F. The

head K is loosely sleeved upon the tubular stem adjacent to the nut thereon, and lateral movement of the head relative tothe nut is prevented by means of lugs t' upon the head, which engage-'over an annular flange j upon the nut. k designates pins secured to the head F, which engage within sockets Z within the head K. These pins maintain the heads in their proper relative position.

Arranged withinnthe stem H is a screw M,

which isfadapted to engage withthe nutJ.

This screw isprovided with a head o, in which is arranged a handle p, and q designates a similar handle upon the stem H.

Thetubular stem H just referred to is prolvided with two locking-lugs O, diametrically arrangedv,.which upon partial rotation within thehead D are adapted to engage with the two Vcorresponding oppositely-arranged lugs P, formed upon the interior of the tubular lhead D to lprevent the lateral movement of the stem within said head.

The mechanism havin g been thus described,

`the operation .of the vise is as follows: The `parts being arranged as in Fig. 2, it will be readily apparent that the operatorie enabled tomove the head K to or away from the complementary head F at will, the lugs being; l v The tube that is to beheld in the-vise is placed within the groove in one ofthe clamping-jaws G and the head K moved into engagement with the tube to be clamped. The movement of the head K produces a correspondinglateral movement of the tubular supporting-stem, so that when the head is in proximityto the jaw G the lock'- ing-lugs upon said stem are at the rear, but jout`of contact with the corresponding lugs upon the interior of the standard. ,To lock the tubular stem to the standard, theformer is rotated one-quarter of a revolution to bring j the oppositely-arranged locking-lugs thereon into engagement with the complementary locking-lugs upon said standard, as shown in Fig. 4. The nal step of clamping is eected by rotating the screw M, which by engaging the nut J causes the head K to move upon.

the lock-supporting stem or arm and to be tightly clamped against the article that is to be held.

In unelamping the vise the screw is first rotated and subsequently the tubular stem is turned.

To more readilyloosen the parts,I form upon the end of the stem II a lug fr, against which the handle upon the screw is adapted to strike. Thus the operator is enabled to unlock the parts by the use of a single device.

\Vhile I have shown and described one of the clamping-heads as swiveled to the standard, I do not desire to be limited to this construction, as it is obvious that both of the heads may be clamped to the said standard by lncans ot' the screw.

What I claim as my invention is- 1. In a vise, the combination with a standard, of complementary clamping members, a rotatable support slidingly engaging the standard and extending through the members, said support being adapted upon lateral movement in one direction to ellect an e11- gagement ot the members about the article to be clamped, complementary locking devices upon the support and standard, and means for rotating the support after its lateral movement, to effect a locking engagement between said locking devices.

2. In a vise, the combination with a standard, of complementary clamping members, a rotatable support slidingly engaging the standard and extending through the members, said support being adapted upon lateral movement in one direction to effect an engagement of the members about the article to be clalnped, means for rotating the support after its lateral movement, into a locking engagement with the standard and means for subsequently sliding one of the members upon the locked support to clamp the article.

3. In a vise, the combination of a standard, a support slidingly engaging the standard for free endwise movement in either direction, a nut upon the support secured to the latter against rotary movement, a clamping member sleeved upon said support adjacent to the nut, a complementary clamping member arranged intermediate the sleeved member and the standard, means for locking the support to the standard after the engagement of the clamping members about the article has been effected and a screw engaging the nut adapted when actuated toelamp the members to the article. Y

4. In avise, the combination of the standard, a tubular head thereon, a support arranged within the head having free endwise movement in either direction, a n ut upon the support secured to the latter against rotary movement, complementary clamping-heads sleeved over the support intermediate the nut and standard, means for locking the support to the standard after an engagement has been effected between the clamping-heads and the article to he held, and a screw engaging the nut adapted when actuated to clamp the head to the article.

5. In a vise, the combination of the standard, a tubular head thereon, a tubular supporting-arm arranged within the head for free endwise movement in either direction, a nut upon the support, complementary clampingheads sleeved over the supporting-arm intermediate the nut and standard, means for locking the arm to the standard and a screw within the tubular arm engaging the nut upon the latter.

(j. In a vise, the combination of the standard, a tubular head thereon having a lockinglug formed upon the interior thereof, a support arranged within the head for rotary and free endwise movement in either direction, and provided with a lug adapted to be engaged with the lu g, within the tubular head, a nut upon the support, complementary clamping-heads sleeved over said support intermediate the nut and standard, means for rotating the support and a screw engaging the nut adapted to clam p the heads about the article.

7. In a vise, the combination of the standard, a tubular head thereon, a supportingarm arranged within the head having free endwise movement in either direction, a nut upon one end of the supporting-arm, a clamping-head loosely sleeved upon the arm, a complementary head swiveled to the standard, means for locking the arln within the tubular head and a screw engaging the nut adapted to move the sleeve-clamping head upon the locked support.

8. In a vise, the combination of a standard, a tubular head thereon, a supporting-arm arranged within the head having free endwise movement in either direction, a nut secured upon one end of the arm, a clamping-head sleeved upon the arm and swiveled to the nut, a complementary head swiveled to the standard, means for locking said latter head to the Standard, mechanism for locking the arm within the tubular head and a screw engaging the nut adapted when actuated to clamp the heads about the article.

9. In a vise, the combination of a standard, a tubular head thereon, a supporting-arm arranged Within the head having free lateral movement in either direction, a nut secured upon one end of the arm, a clamping-head provided with a multiple of clamping-jaws sleeved upon the arm and swiveled to the nur, a complementary head carrying a multiple of elamping-jaws thereon, swiveled to the standard, guide-pins connecting the heads, means for locking the arm Within the tubular head and a screw engaging the nut adapted when actuated to clamp the heads about the article.

In testimony whereof I aflix my signature in presence ot two witnesses.

CLARE ERNST.
